Is it asking you for your password for your e-mail account? Even though you have saved it in you keychain? This was happening to me earlier, I had to enter it 3 times before it worked, kind of annoying.

The password is in the "login" keychain. That does particular keychain have to be locked? It is currently unlocked.

No, it should be unlocked. As ero87 mentioned, I also get this when the e-mail provider is down. I have a Yahoo! Small Business e-mail account that frequently does for a few minutes at a time. Could that be the case here?

i find this sometimes happens when the email service you're connecting to is down. not really mail's fault...

That seems to trigger the Key corruption, but once it's happened (corrupt Key), doesn't seem to matter if the server's up or down. Just my observation over time. Haven't seen this happen in quite a while, though, and as far as I can tell my server's behavior hasn't changed. (running Apple Mail Service, 10.2 Server)
